SPOTLIGHT.

Apnlication filed November 26, 1919. Serial No. 340,919.

To all whom it may concern.

Be it known that I, RALPH E. lVuiLiAMs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Spotlights, of which the following is a specification.

The present invention relates to a spotlight and particularly to a construction for attaching the reflector of a spotlight to the carrying member. It is an object of the invention to provide a simple, inexpensive, and effective construction by which the reflector of a spotlight may be attached to the carrying member.

A. feature of the invention is the provision of a construction or arrangement by which the reflector of a spotlight is permanently, solidly, and neatly connected to the carrying member. The construction provided by the present invention is such as to cause the joint between the reflector and the carrying member to be particularly tight and solid. The joint is swedged and holds the reflector so as to prevent its working loose or slipping relative to the carrying member.

There are further objects and features of the invention which will be best understood from the following detailed description of a preferred embodiment of the invention throughout which reference is had to the accompanying drawings in which- Fig. 1 is a side elevation of a lamp embodying the present invention; and Fig. 2 is an enlarged vertical section of the same.

Throughout the drawings numeral 10 designates the carrying member to which is connected the reflector 11. The carrying member 10 may be of any design or construction common to devices of this general character. For instance, it may be provided with a central longitudinal bore 12 and may be provided with a suitable spindle 13 by which it may be connected to or mounted on a bracket of any kind.

The reflector 11 may be of any desired design or construction, the particular reflector shown in the drawings, however, being a single shell the inner surface 14 of which is highly polished or finished so as to form a reflecting surface.

In the particular form of construction shown in the drawings a flange member 15 is adapted to be carried on the forward end of the mounting member 10 so as to abut or engage the rear surface of the reflector 11. The flange member 15 is preferably pressed metal and forms a backing for and reinforces the reflector 11. The flangemember 15 is made soas to slide freely over reduced portion 16 at the forward end of the mounting member and is adapted to engage and press against shoulder 17 formed in the mounting member as clearly shown in Figs. 2 and 4:.

The reflector 11 does not necessarily connect to the flange member 15 but connects directly to the mounting member 10. The reflector 11 has a cylindrical rearwardly extending portion or neck 18 which is adapted to extend into an enlarged portion 19 of the bore 12 at the forward end of the mounting member 10. An annular recess or groove 20 is formed in the enlarged portion 19 of the bore 12 and the neck 18 of the reflector is adapted to be pressed or expanded into the groove 20 as clearly shown in Figs. 2 and 4:. The neck 18 of the reflector 11 is preferably expanded into the recess 20 while the mounting member 10 and the reflector 11 are being forced .or pressed together. It will be readily understood that when, the neck 18 is expanded or swedged into the recess 20 while the mounting member 10 and reflector 11 are held or forced together, the mounting member 10 and the reflector 11 separate, after the pressure is taken off of them, thereby causing the connection between the mounting member 10 and the reflector 11 to tighten. This is due to the fact that the swedged or expanded portion of the neck 18 is drawn or forced more tightly against the wall 21 of the groove 20. This form of joint between the mounting member 10 and the reflector 11 and this manner of forming or making the joint or connection have been found in practice to be particularly eflective, durable and inexpensive.

It is to be understood that the construction of the present invention may be made or formed in any desired manner and that the invention is not in any way limited to any method or apparatus that may be employed in its formation or assembly.

Having described a preferred embodiment of my invention I do not wishto limit myself to the specific details hereinabove set Having described a invent-ion, I claim:

1. In a lamp, amounting member having a grooved bore, and a reflector attached to the mounting member, the reflector having a neck sWedged into the grooved portion o'f-the bore of the mounting member.

preferred form of my 2. A lamp comprising a mounting member having an annularly grooved bore, and a reflector attached to the mounting member, the reflector having a neck extending Into the bore and expanded into the annular groove.

3. A lamp comprising a member having a RALPH E. WILLIAMS.
